ACID-COOLING TOWER.

SPECIFICATION forming part of Letters Patent No. 645,235, dated March 13, 1900.

Application filed July 12,1899. Serial No. 723,556.l (No model.) i

To @ZZ whom it may concern:

Beit known thatI, CONSTANTIN RUGGAEER, a citizen of the United States, residing at Richmond, in the county of Henrico and State f Virginia, have invented certain new and useful Improvements in Cooling-Towers for Sulfuric-Acid Gas; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful im- .provements in cooling-towers for use in the manufacture of sulfuric acid; and it consists in the provision of means whereby the gas is caused in its ascent to come into contact with cold-water coils which are disposed in the various shelved compartments of the tower, whereby the gas becomes condensed when it reaches the upper portion of the series of cooling-coils. A

More specilically the present invention resides in the provision of a cooling-tower made of suitable masonry and having a suitable acid-resisting lining and provided with a series of shelves dividing the interior of the tower into a series of compartments, with alternately-disposed openings at the sidesof the inclosure, whereby the gas is made to travel back and forthl from one compartment to another in its ascent, thus bringing it in contact with separate cooling-coils, one or more in each compartment. YIn connection with the foregoing a lead water-jacketsurrounds the lower portion of the tower, where the gas at its highest temperature enters the cooling-chambers.

To these ends and to such others asthe invention may pertain the same consists, further, in the novel construction, combination, and adaptation of parts, as will be hereinafter more fully described and then specifically defined in the appended claim.

My invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a partA of this application, and in which- Figure lis a central vertical section through the tower. Eig. 2 is a sectional view horizontally through the tower.

Reference now being had to the details of the drawings vby letter, A designates the wall of the tower, made of masonry and surrounded, preferably, with a sheathing of lead B and lined with an acid-proof material, as at O. The interior of the inclosure formed by the outside walls is divided into a series of compartments by means of the shelves or partitions D, and the free edges of these shelves are arranged alternately to one another, as shown in the drawings, whereby lthe gas is made to travell the entire width of the tower in passing from one compartment to another in its ascent. The bottoms of these shelves or partitions are made, preferably, of a tiling or other acid-resisting.materiaL and in the shelves is a series of perforations d, which are provided primarily to allow the interior of the tower to be washed out.

The gas enters the tower throughv the opening E, to which a pipe may be connected, and surrounding the lower portion of the tower is a cooling-receptacle F, made, preferably,

rof sufficient height to extend vup above the portion into which the gas enters at its high-v est temperature. Through this .receptacle the pipe leading to the opening E is designed to passgas-tight. This pipe, however, does not show in the drawings. Leading away from the upper end of the tower is a pipe R, through which the gas is allowed to escape.

Between each shelf is a coil of lead pipe G, which is connected with a vertical pipe H, through which water passes to the coil. Each coil is separate from the other and each has a separate outlet-pipe K, whereby the water in the various coils, when it has become heated from absorbing heat from the gas, may run freely out and fresh cold Water run through the coils.

At the upper end of the tower'is a pipe M, from which lead 'jets on, through which weak acid may be allowed to come in contact with the partially-condensed gas which rises to the top of the tower.

From the foregoing it will be noted, when taken in connection with the drawings, that I produce an apparatus for making sulfuric acid, nitric acid, and other acids for which IOC) the device may be applicable by the employment of the smallest amount of space possible. The gas becomes quickly cooled, and the apparatus may be washed out by the peculiar arrangement of the perforated shelves.

Having thus described my inventiomwhat I claim to be new, and desire to secure by Let# Y ters Patent, is-

A cooling-tower having walls of masonry with outer sheathing of lead and mounted on a, suitable platform, a series of alternatelyarranged perforated shelves supported on the inner walls of the toWer,e water-coolingjaeket surrounding the portion of the tower below the bottom of said shelves, the inlet-pipe passing water-tight through the walls of said jacket and sheathing, and the coils between each shelf, the outlet end of each coil being downwardly disposed and positioned to discharge into said cooling-jacket, all as shown vend described Vand for the purpose set forth.

In testimony whereof I affix my signature 1n presence of two Witnesses.

CONSTANTIN RUGGABER.
